CARROLL, OF YONKEBS,NEW YORK, ASSIGNORS TO THE TABULATING MACHINE COMPANY, OF ENDICOTT, NEWYOR K, A CORPORATION OF NEW JERSEY I ram'rme mavrca non raauLa'rTNeMACHINES Application filed May 27,

This invention relates to automatically controlled accounting machinessuch as tabulating machines in which entries upon a recerated mechanismsfor effecting the printing of additional matter such as account namesand a common heading such as are provided upon bills. a

With respect to the improvements it is also an object to include deviceswhereby the account name printing devices, preferably in the form ofstencils, are fed but are analyzed so that only the desired oneidentifies the related items and totals printed. Preferably theimpression devices are compared with the item controlling devices soth'at printing of the wrong identificat on data will be prevented.

In connection with the printing devices for printing the common headingthe object is to include automatically operated devices for printingthis data when the other printing operations have been performed so thata completely printed bill may be effected.

It is also an additional object to provide severing devices which detachthe printed portion from the remaining part of the strip toautomatically make up separate bills for distribution according to thesystem adopted.

T these and other ends the invention consists in the novel features ofconstruction, arrangement of parts, and combination of elementshereinafter described and more particularly set forth in the claims.

Referring to Fig. 5 it will be observedthat the present inventioncontemplates printing a common heading'upon a section of a long web toprovidea heading for a bill, a series of items represented by a seriesof controlling cards correspondingly classified, a total thereof, andmeans for printing variable data, such as the name of an account whichis only printed upon the bill receiving correspondingly classifieditems.

7 The present improvements are illustrated herewith in connection with atabulating machine of the form fully shown and described inthe patent toC. D. Lake, No. 1,379,268, dated May 24, 1921. The particular type ofmachine does not enter into the present invention as any other form ofentry receiving device. would serve the purpose of explanation andembodiment equally as well.

As more fully explained in the Lake Patent 1,379,268 a stack oftabulating records which represent the items of the various accountsindicated by numeral 10 (see Fig. 6) are advanced singly by a picker 11operated by an arm 12 and are thus drawn into cooperative relation witha pair of feeding rollers 13. The picker feeds one card at a time to therollers 13 which advance a card during onemachine cycle to the upper orcontrol brushes 14 and during a later machine cycle to the lower oradding brushes 15. The rollers and feed mechanism are driven from ashaft 16 rotated by the usual tabulating motor and gear train indicatedgenerally by reference character 17. As the perforated cards are fed tothe adding brushes the index points are sensed in the usual manner inorder that the printing type 18 (Fig. 2) may 100 be differentiallycontrolled. Item and total printing operations are effected by impellingthe selected type against the usual roller platen 19, impressions beingeffected upon the record strip 20 by the customary inking ribbon. Asmore fully explained in the Patent 1,762,145 to Daly et al., and showndiagrammatically in Fig. 6, the lower brushes 15 are adapted to beplugged so as to control printing control magnets 10a and adding magnets9a. Printing control magnets 10a are adapted to selectively call theitem type 18 (Fig. 2) into operation to print the values represented bythe perforated cards. Upon a change in group designation determined bybrushes 14 and 15 a total operation will ensue and contacts 120 (Fig. 6)will close at different points in the cycle depending upon the positionof stepped cams 11a. The latter, as more fully described in the patentlast cited, is adjusted under control of the adding elements controlledby adding magnets 9a. The closure of such contacts 12a will therebyenergize the printing control magnet 9a at a certain point in theoperation so that by a plurality of magnets ea the same printing type 18are differentially controlled to effect a total print on the recordstrip 20, as are used for item printing. During item listing operationsa shaft 21 (Fig. 1) is operated to drive the various mechanisms.

- It should further be explained that each record card carries a groupof perforations representing a particular classification or groupnumber. These perforations are sensed by brushes 14 and 15 but when acord having a new group number is presented to the brushes 14, itemprinting is terminated and the control mechanism more fully illustratedin the patent to C. D. Lake, No. 1,600,413, dated September 21, 1926,conditions the machine for a total taking operation. During thisoperation shaft 21 is idle but a total taking shaft 22 (Fig. 1) isdriven to operate various mechanisms as an incident to total printingoperations.

Any suitable paper strip spacing mechanism may be provided for effectingpaper spacing operations such as, for example, the type disclosed in thepatent to Daly and Page 1,762,145 dated June 10, 1930 and F. M. Carroll,Serial No. 287,549, filed June 22, 1928 to which reference may be hadfor further details of construction and operation. The paper strip 20(Fig. 1) is drawn from a supply roll, thence passes about a tensionedroller 23, fixed rollers 24, around the platen 19 and thence betweenpairs of feeding rollers 24a and 246 (Fig. 3). Feeding rollers 24a aredriven intermittently as an incident to item printing operations tosuitably space the items as shown in Fig. 5. The paper strip 20 is,however, preferably given a greater spacing before and after totalprinting operations in order that the total be printed on somepredetermined line and to provide space to accommodate the variableidentifying data 25 exemplified herewith as account names. Such printedmatter identifies the data which follows below, and which preferablycomprises a series of items with arelated total.

In the present instance the identifying data is printed by a member 26(Fig. 4) which may be a matrix, token and of any suitable material butis exemplified herewith as a plate carrying stencilled data for printingnames of account, and, in addition, preferably carries perforations 27representing an arbitrary account number. 7

For the purpose of successively feeding the printing plates 26 which areinitially stacked as shown in Fig. 2, a bar 28 slidably mounted in aframe 29 is provided. The bar 28 carries spring urged picker members 30,a pair of which engage the front and rear edges of the lowermost plate26 to positively means may be provided to hold the plate fed' in thismanner impositively on the upper surface of frame 29 while the bar 28and picker members 30 are returned to normal position. It will beobvious that when the next plate at the bottom of the stack is fed, theplate previously fed will be moved a step to the right (as viewed inFig. 2) the arrangement being such that three feeding operations arerequired to move a plate 26 from the stack to a gripper to be presentlydescribed.

Under certain conditions bar 28 is automatically reciprocated as anincident to a total taking operation by the following mechanism: Bar 28(Fig. 2) carries a pin 31 engaging a bifurcation of a lever 32 at an enddistant from its connection to a rock shaft 33. Shaft 33 has secured toit an arm 34 havin a pin 35 engaging a closed slot 36 of a link 3articulated to a spring urged bell crank 38 whose roller 39 cooperateswith a cam 40 attached to a sleeve 130 which, if the required agreementbetween a tabulating card and printing member 26 is effected is clutchedto a shaft 41 driven during each total taking operation. Shaft 41(Fig. 1) carries a bevel gear 42 meshing with a similar bevel gear 43mounted Shaft 55. Splined to the shaft 55 by a key 56 is a yoke shapedplate gripper frame 57 the side arms of which carry their respectivegripper arms 58 pivoted at 59 and urged towards each other by aconnecting spring 60.

Pinned to shaft 55 is a pair of mushroomshaped cams 61 engaging theextensions 62 of the respective arms 58, it being clear that as shaft 55is shifted the free ends of arms 58 will be moved away or towards eachother, and that the angular position of frame 57 is dependent on theposition of shaft 55, and furthermore, the various positions of gripperarms 58 and frame 57 may be assumed independently of each other toperform the necessary operations.

Since the shaft 46 is rocked by cam 50 it will also be clear that theposition of shaft 46 also controls the position of the arms 53 and theparts carried thereby.

In order to provide for the necessary positioning of arms 58 by shiftingshaft 55 the followmg mechanism is preferably emplo ed.

Attached 'to sleeve 130 is a cam 63 ig. 3) coacting with a rollercarried by an arm 64. Integral with arm 64 is an arm 65 which isconnected to one arm of a bell crank'67 by a twisted link 66 (see alsoFig. 7). The other arm of hell crank 67 is connected to a link 68 (Fig.7) carrying a stud 69, engaging an annular groove of a sleeve 70slidably mounted on shaft 46. Also slidably mounted on shaft 46 butsecured to sleeve 70 is an arcuate rack member 71 meshing with a pinion72 attached to a shaft 73. Shaft 73 is journalled in brackets 74 and 75secured to arm 53 and carries at the other end a similar pinion 76meshing with a similar arcuate rack member 77 pinned to the shaft 55.Through the-train of mechanism just described cam 63 effects the desiredshifting movement of shaft 55 to open or close the jaws or gripper arms58.

In order to effect the desired rocking movement of shaft 55 a cam 78(Fig. 2) secured to sleeve 130 is provided. This cam coacts with aroller 79 carried by an arm 80 the upper end of the arm being attachedto an arm 81 by a link 82.

As shown in Fig. 7, arm 81 has a splined connection 83 to a shaft 55 thearm 81 being confined by bracket extensions 84 of the bracket 75.Attached to shaft 55 is an arm 85a (Fig. 2) biased by a spring 86aacting to hold shaft 55 in a position determined by cam 78.

When the parts are in their normal position, as shown in Fig. 3, thejaws 58 firmly grip the plate from which the next printing is to beeffected. IVhen the sleeve 130 is driven, cam 50 is almost immediatelyeffective to rock shaft 46 to lower arms 52 and 53 and parts carriedthereby until shaft 55 occupies its lowest position, illustrated bydotted lines in Fig. 2. As the parts are thus downwardly extending arms86 (Fig. 2) integrally connected at their lowermost ends by a crosspiece 87 to which is affixed an inked felt pad 88.

Also secured to shaft 85 is an arm 89 (Fig. 2) connected to'a camoperated bell crank 90 by a link 91. The roller carried by one of thearms of the bell crank 90 coacts with a cam 92 secured to sleeve 130.When the plate 26 occupies the proper printing posi- 7 tion the highpart of the ca1n92 is effective to rock the yoke 8687 and inked pad 88against the plate and directly over the stenciled name portion to thusproduce a like impression 25, (Fig. 5) on the record sheet 20 whichsuitably identifies the matter previously printed.

' When the inked pad 88 has been moved reversely out of the way the cam50 is then effective to elevate shaft 55 to the uppermost dotted lineposition, cam 78 being effective during this time to rock the shaft 55to bring v the seized printing plate directly in front of the stackedplates 26 from which printings have already been effected. A continuedrocking movement of shaft 55 will force the seized plate behind pairs oflatching arms 93, 94 (Figs. 2 and 7) to hold the plate in stackedposition. The latching arms are secured to their respective supportingshafts 95, 96 and are urged towards each other by a spring 97 (Fig. 3).In order to accommodate the grippers 58 the side plates 98 of thereceiving chute are cut away at 99 as clearly shown in Fig. 3.

After the plate is in stacked position the cam 63 (Fig. 3) is theneffective to separate the grippers 58 releasing their hold on thestacked plate 26. At the termination of this cycle of events shaft 46 isrestored to its normal position bringing the parts again to the positionshown by full lines in Fig. 2, the grippers 58 now being drawn towardseach other to receive a new printing plate which is 7 fed to thegrippers during the time the grippers are in horizontal alignment withthe plate being fed thereto.-

As the record cards carrying group classification are sensed by thebrushes 15 the perforations are compared with the group classificationperforations 27 of the printing plates 26 and if the perforationscompletely agree further operation of the machine will ensue. Referringto the circuit diagram in Fig. 6 it will be observed that current to thebrushes and various relays is supplied by main lines 100 to 101.

From main line 100 a wire 102 leads to a metal block 103 carryingbrushes15 each of which continues the circuit connection to an individualsegment plate 104 througha peroration in a record card. The circuit thenextends by a jumper connection 105 to the relay magnet 106 when a air ofreading levers 107 and 108 are electrlcally bridged.

It will be apparent that the circuit connection just described isduplicated for the different denominational orders and while the diagramshows an embodiment for analyzing only three orders, this number may bealtered to coincide with the number of denominational orders of theperforations 27 representing the group classification number of theprinting plates 26.

Each relay magnet 106 when energized is adapted to close its relaycontacts 109 which are in serial connection with a clutch relay magnet110 shunted across the main line wires 100 and 101. Brushes 111 and 112engage the hubs of the reading levers 107 and 108 to provide for acontinuous electrical contact during their movements. (See also Fig. 2).

From Figs. 2 and 7 it will be observed that the levers 108 for thedifferent denominational orders are tied together for synchronousoperation by a rod 113 passing through insulated extensions of saidlevers. Rod 113 is supported at its ends by a pair of arms 1'14 pinnedto a rock shaft 115 which carries another arm 116 (Fig. 1) joined to onearm of a bell crank 118-119 by a link 117. The arm 119 carries a roller120 engaging a profile cam 121 attached to a stub shaft 122. This shaft,by bevel gear connections 123 and 124,

' is driven from the shaft 21 which, it will be recalled is rotated asan incident to each listing operation. Cam 121 is arranged to oscillatethe rod 113 (Fig. 2) during each item listing operation so that thelevers 108 contact index point plates 125 simultaneous with the sensingof the corresponding index point perforation of the record card by thebrushes 15.

Index point plates 125 are in the form of curved spring plates which arewide enough to contact companion levers 107 and 108'when their angularpositions coincide. Normally, the levers 107 and 108 are displaced withrespect to their angular setting by reason of the fact that a spring 126(Fig. 2) connected to an integral extension of each related lever 107rocks the same to engage a laterally projecting insulating block 127attached to the companion lever 108. It will be apparent that as rod 113is rocked, springs 126 will cause levers 107 to follow the movement oflevers 108 until one of the levers 107 is arrested by the engagement ofa reading lever 128 with one of the perforations 27 in the group withwhich it is in alignment. There- 7 upon lever 107 will be stopped and aslever 108 arrives adjacent an index point plate 125 corresponding to aperforation presented to brush 15, levers 107 and108 will beelectrically bridged by one of the plates 125 thus energizing therelated magnet 106 which draws downwardly its armature structure 129(Fig. 2) to close related contacts 109. As each pair of contacts 109 areclosed they are latched in such position by a related latching lever130a and when all of the pairs of contacts 109 are closed the clutchrelay magnet 110 (Fig. 3) will be energized.

It will be apparent that durin and succeeding listing operation t ereading levers 128 (Fig. 2) will be drawn over the printing plate 26until each lever 128 engages a perforation 27. Due to the formation ofthe hooked end of the lever 128 the related lever 107 will be stopped inits movement when the lever 128 enters a perforation.

Companion levers 108 continue to contact the remalnlng contact plates125 of the series but upon the return thereof they pick up and returnsuch levers 107 that have been arrested by the perforations 27, levers128 being merely carnmed out of such perforations to be brought to thenormal starting position. The particular card 26 which is analyzed byreading levers 107-108 constitutes the one fed from the stack during theprevious total prlnting operation, and although the card is successivelyanalyzed during each item printing or listing operation the clutch relaymagnet 110 is energized during the first listing operation. if the groupclassification perforations in the record cards and printing platesagree in all orders. If theprinting plate 26 does not correspond to thegroup classification of record cards magnet 110 will not be energizedand the machine will be stopped in its operation, as will be describedhereinafter.

As previously stated when the group classification of successively fedrecord cards change, the machine is conditioned for total takingoperations and in the event that the classification of the group ofcards analyzed is identical to the group number represented by theperforations. of the printing plate in analyzing position, clutch magnet110 will be energized to cause an operative connection between thedriven shaft 41 and the cam carrying sleeve 130 (Figs. 3 and 7). Thebevel gear 42, previously described, is secured to shaft 41 which alsohas secured thereto a disk 131 (Fig. 3) having a cam notch 132 in itsperiphery normally engaging a pawl 133 carried by a disk 134 secured tothe sleeve 130. A tail of pawl 133 normally underlies a pin 135 carriedby an upstanding arm of the armature structure 136 of relay magnet 110.

the first It will be evident that when the pin 135 coacts with the tailof the pawl the cam notch 132 will cause the tail to be disengaged from,

the disk as the latter rotates during a total taking operation. However,if magnet 110 should be energized under the conditions pre viouslystated the pin 135 will be disengaged from the tail of the pawl 133 andthe latter will cause disk 134 and sleeve 130 to be driven a completerevolution to perform functions previously described.

Contacts 109 are opened to deenergize magnet 110 after the clutchconnections have been permanently established causing pin 135 tosubsequently engage over the tail of pawl 133. Underlying tails of thelatching levers 130a is a bail 137 (Fig. 2) which is connected to a bellcrank lever 138 by a link 139. One arm of the bell crank lever 138 is inthe plane of a pin 140a. secured toa disk attached to shaft 41 so thatas the pin 140a contacts the bell crank lever the link will be rockedresulting in rocking the bail 137 and latch levers 130a, the unlatchedcontact springs 109 opening under their own resiliency thus deenergizingthe clutch relay magnet 110.

In order to prevent the machine from continuing its operation in theevent that a wrong plate is fed, or failure of the feeding of a plate,the present invention contemplates the provision of certain electricallycontrolled precautionary devices.

As more fully disclosed in the Lake Patent No. 1,379,268 the maintabulating motor is provided with an emergency or record controlled stopcircuit and preferably included in this circuit are two pairs ofserially connected contacts 140 and 141 (Fig. 3).

Upon closure of both contacts operation of the tabulating motor may beinitiated but upon opening of either pair, operation will be inhibited.The machine also includes a card operated lever 142 the tail of which isadapted to engage the upper surface of a printing plate or matrix as itis fed to the B position to thereby rock the lever to close contacts140. Asimilar card operated lever 144 is adapted in the same way toclose its related contacts 141 only when a plate is fed from the Bposition to the C position.

It will be observed in Fig. 3 that card lever 142 engages theintermediate plate in the B position while card lever 144 engages theone fed in advance of the preceding one which is now in the C position;or stated in other words, at the end of the first three card feedingoperations, one manual and the other the result of two subsequent platefeeding operations occurring in two total printing cycles, there will bethe plate first in the C position seized by grippers .58 and engaged bycard lever 144, (Fig. 3) an intermediate plate in the B position engagedby card lever 142 an the last plate fed, in the A or reading position(Fig. 2) and ooacting with reading levers 128.

To start the tabulator without any printing plates physically contactingwith card levers 142 and 144, the following mechanism is provided. A pincarried by a lever 145 secured to a shaft 146 is adapted to cooperatewith the longer contactplate of contacts 140 and when urged in acounter-clockwise direction is adapted to close contacts 140. A similarset of parts comprising a pin carried by a lever 147 secured to rockshaft 148 is associated with contacts 141. Closure of the contacts is,however, prevented by latching levers 149 and 150 engaging the tails ofthe respective levers 145 and 147, which condition exists after a totaltaking operation.

Closure of contacts 140 and 141 by unlatching of the levers 145 and 147is arran ed for when the first printing plate of a stac is manually fedto the A or reading position.

In ali nment with a pin 151 carried by the arm 32 Fig. 3) is a shoulder152 of an externally operably slide 153. When the slide is pushed itresults in rocking shaft 33 to accomplish a feeding operation asdescribed heretofore to cause the bottom plate of the stack to be fed tothe A or reading position. As the slide is operated pins 154 carriedthereby coact with tails of latching levers 149 and 150 respectively, todisengage them from their related levers 145 and 147. Attached to an armsecured to shaft 146 is a link 155 biased by a spring 156 to rock lever145 to close contacts 140 when the lever 145 is released. Similarly,attached to an arm secured to shaft 148 is a link 157 biased by a spring158 provided for the purpose of closing contacts 141 associatedtherewith in a similar manner. It will be obvious therefore, thatpositioning of the first plate to the A or reading position will closecontacts 140 and 141 to permit op eration of the tabulator.

It will be clear that when the operator starts the tabulator the listingof items represented by the record cards will then ensue, item printing,of course, being performed at the printing line determined by platen 19,and the record strip being spaced an increment each listing operation.Upon a change in group classification of controlling record cards themachine will be conditioned for a total printing operation, which willthen ensue. If the groupvclassification of both record cards and theanalyzed printing plate in the A position agree in all orders, relaymagnet 110 will be energized, resulting in feeding the second lowestplate from the stack to the A position. The plate previously analyzedwhich was in the A position will then occupy the intermediate or Bposition, physically contacting lever 142 to retain contacts 140 closed.

After the co-operation of le'ver 142 with the first plate fed, a pin 160carried by disk 131 will engage one arm of a bell crank lever 161connected to link 155 restoring lever 145 to ineffective latchedposition.

It will be observed that no plate has yet reached lever 144 in the Cposition so that it is ineffective to close contacts 141. Secured toshaft 41 is a pinion 162 driving a gear 163 with a two to one ratio,gear 163 carrying apin 1'64 adapted to contact, by reason of the gearratio selected, during only the second total printing cycle one arm of abell crank 165 secured to link 157. Therefore, it will be apparent thatsince pin 164 does not operate arm 165 duringthe first printing cycle,the lever 147 will not be latchedand thus be effective to keep contacts141 closed, permitting the machine to operate for a second series oftabulating operations. The proper starting position of pin 164 may becontrolled eflecting idletotal printing cycles by depression of aspecial total and reset key number that may be accommodated on each worksheet the paper strip is supplementally fed after the last item prlntedto provide for printing the total at a predetermined line, which isgenerally at the bottom of a sheet. A type of paper feeding mechanismthat Will provide for the above is shown fully in the copendingapplication of F. M. Carroll, Serial No. 287,549, filed J une 22, 1928,to which reference may be had for further details of construction andoperation.

It will be observed that printing of items and totals takes place at aline distant from the printing line of the identifying matter, requiringseveral accounts be printed before any account is identified by printingfrom its related printing plate. While an account is printed, therelated plate is in analyzing position. When the subsequent or secondaccount is printed, the plate related to the preceding account occupiesan intermediate position, the first printed account on the recordstrip-20 then occupying an intermediate position with respect to theprinting lines determined by platen 19 and inked pad 88. When the thirdaccount is printed the record strip will be advanced sufficiently topermit printing by the related plate which has now been fed to thegrippers 58 and which is brought to the printing line during the thirdprinting c cle.

It will be recalled that while pin 164 is ineffective to cause therestoration of lever 147 to latched positionto permit contacts 141 toopen atthe termination of first total printing cycle, it is effectiveduring the subsequent, or second total printing cycle. At this time,however, a plate is incooperation with the card lever 144 causingcontacts 141 to be retained in closed position, and, in fact card levers142 and 144 will keep contacts 140. and 141 closed. as long as properprinting plates are fed. In the event that a wrong prmting plate is fedoperation is discontinued direct- 1y thereafter. The manner in whichthis is performedis as follows:

In the event that group classification perforations of the printingplate and record cards do not agree clutch magnet 110 will not beenergized and therefore, no plate feeding operation will take place. Themachine will, however, be conditioned for a total taking operation thusdriving shaft 41.

Pin 160, will therefore relatch arm 145 if it is not already in suchposition where it is ineffective to keep contacts 140 closed, and sinceit is assumed in this case the first plate is manually fed, it willremain in the A-or analyzing position, and card lever 142 will not beengaged by a plate to close contacts 140. At the termination of thetotal taking cycle, operation of the machine as far as tabulation isconcerned, will be discontinued until the proper plate is placed inposition and tabulating in connection with the group of previouslytabulated record cards and proper plate again resumed.

Up to this point there has been described the automatically operateddevices which effect the listing upon a part of the strip a series ofitems representing accounts designated by a series of perforated recordsthe total thereof, and in addition, the printing of the account nameduring a total taking operation contingent upon an agreement between theclassification of the printing plate and the classification data of thetabulating cards. In addition to the above the illustrative embodimentalso includes an arrangement for printing a common heading on theprinted strip after it has received theimprint of the items, total andaccount name. Preferably, the printed part is severed from the stripthus making a complete bill ready for distribution.

To this end the strip 20 (Figs. 2 and 8) after it emerges from betweenthe rollers 24b passes over rollers 175, 176 and between feeding rollers177 which are driven to frictionally take up the strip 20 a suflicientamount during each machine operation 'to cause it to be taut between thepair of rollers 177 and roller 176.

Referring to Fig. 8, carried by a pair of arms 178 secured to a shaft179 is an electro plate 180 carrying raised characters for printing theupper four lines (with the exoeption of the account name, John Smith)upon the bill shown in Fig. 5.

The electro is adapted to be shifted against the strip 20 but previousto this the printin elements are inked by a roller 181. This ro lerisdrawn downwardly by springs 182 to contact the electro and in thepreferred embodiment the roller is carried by a frame 183 secured to arock shaft 184.

The inking plate 185a, by which the roller 181 is inked, is supported bya pivot rod 185 freely rotatable in the frame 186 so as to be capable ofbeing intermittently turned to effect efiicient inking operations.

At the initial operation of the machine during a total taking operation,which as previously stated, is initiated upon an agreement of theperforations in the identifying printing plate and the record cardstabulated, the inking roller 181 is first removed out of contact withthe electro plate 180. In the present cases, this is effected by a camwhich is secured to the sleeve 130 which as previously stated is turnedduring each total taking operation. Secured to the shaft 184 is an arm187 which is connected to an arm 188 through a link 189. The arm 188 issecured to a rock shaft 190 which has depending therefrom an arm 191carrying a roller coacting with a cam race 192 of a box cam secured tothe sleeve 130. During an initial rotation of the cam in the arrowdirection (Fig. 2), link 189 will be shifted upwardly thereby shiftingthe frame 183 to the right and forcing the inking roller 181 over theelectro plate 180 to re-ink the latter. After the roller 181 passes outof cooperation with the electro plate 180, it is then rolled over thesurface of the inking plate 184a so that its periphery picks up the inksupply on the plate. 7

As premised hereinbefore the frame 178 which carries the electro plate180 is secured to a shaft 179 and secured to the latter is an arm 193which is articulated to a link 194 which, at its upper extremity isconnected to an arm 195 loosely mounted upon the rock shaft 190.Connected to the electro plate carrying frame 178 is a spring 196normally tensioned so as to cause, through the connecting link 194 justdescribed, the constant engagement of a roller 197 secured to arm 195with the periphery of a cam disk 198 which is also secured to the sleeve130. The formation of the cam disk 198 is such that after the roller 181is out of contact with the electro plate 180, it will cause the arm 1.95to be elevated, drawing link 194 upwardly and thereby shifting theelectro plate 180 to the left in immediate contact with the strip 20,the lower part of which was previously imprinted with the account name,item and total.

When the electro plate 180 is in contact with strip 20, a roller 199 isrolled over the strip forcing the latter against the raised type of theelectro plate and effecting the desired printing impression. Previous tosuch operation, it is desirable that the electro plate 180 be locked inits shifted position so as to rigidly hold it and preventing its beingshifted when the roller 199 is passing over the strip 201 to effect theprinting impression. To this end there is secured to a rock shaft 200 apair of hook shaped locking arms 201 which are lowered to engage asuitable portion of the frame 178 to hold it at its upper end. One ofthe hook-shaped arms 201 has an upward extension by which it isarticulated to a link 202 pivoted at its upward extremity to one arm ofa bell crank 203 loosely mounted upon the rock shaft 190. The bell crank203 carries a roller 204 which is in constant engagement with asupplerlrgeantary profile cam 205 secured to the sleeve The continuousengagement of roller 204 with the profile of cam 205 is effected bymeans of a spring 206 interconnected with a fixed part of a frame andone of the hook shaped members 201. The formation of the cam 205 is suchthat it permits the hooked arms 201 to be lowered against the action ofspring 206 to thereby hold the electro carry-,

ing frame 17 8.

Subsequent to such operation the printing roller 199 is rolled over thestrip as previously stated. In the preferred embodiment the roller 199is carried by a pair of arms 207 which are dependently carried by a pairof arms 208 each loosely mounted upon the rock shaft 190, one of saidarms 208 having a depending integral arm 209 carrying a roller 210 inengagement with the race 211 of a box cam secured to sleeve 130. Therace of the box cam is so designed that it will cause arms 208 to bepositively shifted-down wardly causing roller 199 in its rolling actionto force the strip 20 against the inked electro plate effecting thedesireddepression therefrom.

Prior to the restoration of electro plate 180 to its normal position,and after the printing impression has been effected, the hook-shapedarms 201 are elevated under action of the associated cam 205.

After the printing impression has been effected the electro plate 180 isshifted to its normal position. (Shown in Fig. 8.) This is done, ofcourse, after the roller 199 has been lifted upwardly to its normalposition. During the last part of the machine operation the cam whichcaused the inking roller 181 to be shifted out of cooperation with theelectro plate 180 now causes the frame 183 to be restored to the leftrolling the inking roller over the inking plate 185 and again in contactwith the electro plate 180 re-inking the same for a subsequent printingimpression.

To intermittently turn the inking plate 185 an incident to each printingoperation there is secured to the rock shaft 184 an arm 212 whichcarries a pawl 213 spring urged into .ment is well known in the printingart no further description of its operation or details of constructionare given herein.

It is also desirable that when all the printing operations have beencompleted that the printed portion of the strip be severed from theremaining part in order to make a sepa rate bill. In the presentinstance, severing is accomplished aft-er the paper feeding operation byrollers 177 by the eoaction of a stationary knife blade 216 with amovable knife blade 217 which is mounted and guided as to pass beneaththe stationary blade 216 to sever strip at the desired line ofdemarcation. The blade 217 may be guided for a linear restoring movementin any suitable manner against the action of a return spring "ariousomissions and 218. Secured to the rock shaft 179 is an arm 219 which isconnected by a link 220 to an arm 221. The arm 221 is secured to a shaft222 which has also secured to it an operating extension 223 adapted tofit within a slot and engage a wall 224 of the guide plate 225 whichcarries the movable knife blade 217. When the operating arm 223 abutsthe wall 224 which is effected by the shaft 179, the movable knife 217will pass beneath the fixed knife 216 to thereby sever the part of thestrip which has been printed.

It is pointed out that the various operations of the machines areperformed during successive machine operations, that is, the items arefirst listed upon the bill and the total thereafter printed if theaccount name on the identifying plate is in harmonious agreement withthe cards tabulated.

Contingent upon such agreement the account name is printed upon the billduring the total printing operation. Thereafter by several machineoperations the strip is fed so that it receives thecommon heading and bya subsequent machine operation is severed by the severing devices justdescribed; However. the aggregate of the machine operations performed onthe strip of paper win .eSult in a completely printed bill ready for distribution in accordance with the system adopted.
